The first is the Megaskepasma erythrochlamys (common name: Brazilian Red Cloak). With leaves that look like the Pisonia but with typical Acanthaceae flowers, its pinkish bracts would definitely stand out in any garden.
The next is a woody climber more often known as Petrea volubilis (synonym: P. kohautiana, P. arborea, P. aspera; common name: Queen's Wreath, Sandpaper Vine, Purple Wreath, Bluebird Vine; Family: Verbenaceae). Not many plants have blue flowers, but this climber does, and there are 2 rings of blue. The common name Sandpaper Vine came about because of its rough textured leaves. Every flower is made up of a ring of 5 smaller dark blue petals with a white patch, which are in turn surrounded by another ring of 5 narrower light blue sepals, collectively known as the calyx. After the petals are shed, the calyx remains. When the calyx dries, it turns brown and when a few of them are broken off from the plant, they spiral as they fall. Sometimes known as the tropical Wisteria, it is truly deserving of its common names and should be planted more in our parks. A link on this plant is shown below:

The next 2 plants are the Hippeastrum cultivar (Family: Amaryllidaceae) and the uncommon Caesalpinia pulcherrima (common name: Peacock Flower; Family: Fabaceae / Leguminosae). The former, together with the pink flower H. reticulatum, are the few Hippeastrums that grow well and continue to flower in our climate and they used to be more commonly planted a decade ago. The latter is different from the common ones in that it has yellow petals and red stamens. This species is a host plant of the Common Grass Yellow butterfly.
